Thalia is an exceptionally brave, strong, and caring girl, though at times she can be profoundly stubborn, prideful, and assertive, like her father Zeus. She likes to be in charge and give out orders to people and becomes angry if they are disobeyed. She also has a bit of a temper. She cares dearly for her younger brother Jason as shown through her joy upon their reunion in The Lost Hero. Hera makes her very upset and she’ll never forgive Hera for separating her from Jason.
